Copper conductors

Temperature measurements up to 400°C.

Mineral insulated RTD cable with copper conductors is a common choice for temperature measurements up to 400°C. Copper conductors have a very stable resistance vs temperature relation. Furthermore, the material is economically priced. These cables are available in the following sheath materials;

  • AISI 304 – 1.4301
  • AISI316(l) – 1.4401/1.4404
  • AISI316Ti – 1.4571
  • AISI321 – 1.4541
  • Inconel 600 – 2.4816

On this page we explain all common used sheath materials and their advantages compared to other sheath materials for MI cable.

Furthermore Okazaki mineral insulated RTD cable with copper conductors are;

  • available in diameters ranging from 1.0mm to 8.0mm
  • available in normal spaced and wide-spaced execution
  • available with 2, 3, 4, 6 and 8 conductors
  • supplied with a material 3.1 certificate
